Enemies/wildlife

Arcterra Gateway is the landing area for the Alimbic planet Arcterra. It is a naturally large and open space, making it an ideal landing place. It is not shielded from the elements, and because of Arcterra's extremely cold weather, the Arcterra Gateway is completely covered in ice and snow. When entering the Arcterra Gateway, Samus's gunship lands on a perch high above the exit door. Samus must follow a steep ice path to get to the bottom.

While escaping the planet after getting the first Octolith, a force field appears above a pillar preventing access to the upper half of the room, forcing Samus to fight Guardians.
